Supply vapor to the carburetor, for internal combustion motors

ABSTRACT

A wick, inserted into a container of water, so arranged that the wick enters the bottom of the duct into the air filter, wick resting in a trough so constructed that the sides and rear of the trough are raised to restrict the suction of water into the carburetor of an internal combustion motor.

PATENTEU JUN29 IHYi FICA- FIGS SUPPLY VAPOR TOTIIE CARBURETOR. FORINTERNAL COMBUSTION MOTORS My invention relates to a means by whichwater is available to be converted into vapor by the introduction ofheated air into the intake of the duct used to supply the air to thecarburetor. The introduction of vapor completely eliminates carbon, theresult being that hydrocarbon and carbon monoxide are not present in theexhaust. Automotive engineers are conversant with this fact.

A further object of this invention is to have a supply of water. soarranged that the water can be converted to vapor, also with provisionthat all excess water will drain out of this duct thereby restrictingany possibility of the water entering the carburetor throat. The amountof water to supply the vapor is controlled by the size of the wickemployed to bring the water up from the water container into the intakeduct.

With the above and other objects in view, the invention consists in thenovel features of construction, arrangement and combination of theparts, hereinafter more fully described and finally pointed out in theclaims hereto appended.

Referring to the drawing:

FIG. I is a side elevation view, showing the water container positionedat the bottom ofthe air intake duct.

FIG. 2 is a plan view, showing the position of the wick in the duct.

FIG. 3 is a side view, showing the position of the wick in the watercontainer.

FIG. 4 is a front view, showing the duct opening to the carburetor andposition of the wick.

FIG. 5 is a plan view of the water'container divorced from the air ductwithout the wick showing.-

Referring to the drawing: 1 designates the wick, 2 designates the trough.and the extension into the water container, 3 designates the watercontainer, 4 designates the cap on the opening for filling the watercontainer, 5 designates the duct to the carburetor, 6 designates the endof the duct to the carburetor, 7 designates the air opening to the duct,8 designates opening in the floor of the duct, 9 designates opening inthe top ofthe water container.

FIG. I is a side elevation view of my invention. 1 designates a wick orany material with capillary attraction. 2 designates a rustproof guideto convey the wick to the bottom of the water in the container, thesection of this guide that extends through the bottom of the air duct isso constructed that the sides and the rear of this guide are raised thethickness of the wick forming a trough, any excess water on this wickwill drain back into the water container. The wick is attached to thisguide in any conventional manner. 5 designates the air duct to thecarburetor. 7 designates the opening to the air duct. 6 designates theair exit to the carburetor.

FIG. 2 is a plan view of my invention. 1 designates the wick afterentering the air duct. 2 designates the guide which is so constructedwith a lip on the sides and rear said lip to be the thickness of thewick. 8 designates the hole cut in the floor of the duct for admittingthe guide and wick into the floor of the air intake duct. 3 designatesthe water container. 4 designates the cap closure for filling the watercontainer. 5 designates the air duct to the carburetor. 7 designates theopening to the air duct. 6 designates the point at which air passes outof the air duct to the air filter or to the carburetor.

FIG. 3 is a side view of the device. 3 designates the water container. 2designates the guide to which the wick is attached. At the top of thisdrawing is shown the raised sides of this guide forming a trough inwhich the wick is positioned. l designates the wick. 4 designates thescrew type filler cap.

FIG. 4 is a view looking into the air duct to the carburetor. 7designates the opening for air to enter the duct. 1 designates the wick.2 designates the guide. 3 designates the water container. 4 designatesthe screw type filler cap. 5 designates the opening for air to enter theair duct.

FIG. 5 is a plan view showing the opening 9 in the top of the watercontainer. 4 designates the filler cap opening for filling the watercontainer. 3 designates the water container.

ln carrying out the invention, it IS my aim to provide a supply of waterin the intake duct, so arranged that by drawing hot air over this watersupply vapor is formed. 1 is shown .as a wick or any material withcapillary attraction. 2 designates the guide to which the wick isattached in any conventional manner, this guide extends from the base ofthe water container 3 up through the water in the container and out atthe top through opening 9 as shown in FIG. 5. The guide 2 is insertedinto the floor of the air duct through an opening of sufficientdimensions to accommodate the guide with the wick attached.

This guide is so constructed that the wick rests in a trough as shown inthe top of FIG. 3, this trough being slightly raised on the sides and inthe rear, to the thickness of the wick, all excess water will drain backinto the water container 3. The air flow is designated by arrows, therear of the trough is raised approximately the thickness of the wickallowing air to pass against the wick but not through the wick. Thisconstruction permits hot air to pass over the wick I and convert thewater to vapor allowing a perfect combustion mixture. Without the raisedsides and rear of the trough it is conceivable that the terrific suctionof the air on the intake stroke could draw water through the wick andallow water to enter the carburetor throat. Any conventional heatingdevice capable of producing approximately F. will extract the moistureon this wick and convert same to heated vapor.

To protect the container of water from freezing add sufficient alcohol.

What I claim:

I. A vaporizer comprising a closed container filled with water, saidcontainer having an aperture in the top thereof, an air duct having aninlet and an outlet, an aperture in the bottom of said air duct, saidcontainer connected to said duct to provide fluid communicationtherebetween through said respective apertures, a guide in saidcontainer and extending through said apertures into said air duct, theportion of said guide in said air duct being inclined upwardly towardsaid air duct outlet, said guide defining a trough having said walls anda rear wall at its uppermost end, a wick extending substantially thelength of said guide and attached thereto, said wick being positionedwithin said trough, the sidewalls and the rear wall of said troughhaving a height equal to the thickness of said wick, means defining anopening in the top of said container and closure cap means for closingsaid opening.
